AUSTIN — The so-called transgender bathroom bill will be publicly debated for the first time Tuesday morning, and hundreds of people from across the state are expected to weigh in.

Members of the Senate State Affairs Committee will debate the bill, Senate Bill 6, which would bar transgender people from using the restrooms, locker and changing rooms that correspond to their gender identity in public schools and government buildings. It would also nix city laws that explicitly protect this access.

By 6:45 a.m., nearly a dozen people had lined up outside the locked Capitol doors to wait for their chance to give public testimony on the bill. Hundreds are expected to come from across the state, with sizable delegations of transgender Texans and their families from Dallas.

The Dallas Morning News will be live-tweeting from the hearing, which will start at 8 a.m. and is expected to last all day and into the evening. The Senate State Affairs Committee will hear expert testimony first, and then will open the debate to members of the public, who will be allowed to speak for two minutes each.
